Domain became unenabled after license update. Unable to reenable (says maximum number of domains has been reached, but this is the only domain we use)

Title mostly describes the issue. We have Axigen setup on a local CentOS 8 machine. After updating the license, we are unable to reenable that domain for use by our employees. The message appears as a red messagebox and says the following:

The maximum number of domain objects (accounts, groups, mailing lists, etc.) allowed by your license has been reached!

After reviewing our license information I found this information:
